Does MacBook Air's ability to connect to WiFi erode over time? Anything I can do to boost the Air's ability to connect to WiFi?
I have Macbook Air circa 2014. Over the past year or so, it is worst performing device in our home when connecting via Wifi to the internet. My wife's laptop, iPad, Kindles, phones, etc., all seem to connect and stay connected without effort, but my laptop consistently has a hard time connecting, and staying connecting.
We have (what I think is) a strong Wifi network with repeaters throughout the home, so I don't think it's an issue of the Wifi available - I think it's an issue with my laptop itself.
Does the ability of a laptop to connect to Wifi erode over time? Is there a way I can diagnosis this myself and/or boost this ability? I didn't see anything immediately obvious in System Preferences.
Thank you!
MacBook Air 13", OS X 10.11
